Robert B. Hayden, Seattle', Wash., assignor to H. L. J.Specialty Co., Seattle, Wash., a corporation of Washington I Application January 26, 1932, Serial-No. 588-,948 o`1aims. (oido-14) 'My inventionrelates to improvements `inrlocksandthe primary object of my inventionis to provide a lock of extremely simple and cheap construction which is especiallywell adapted for use 15.1 on small individual money banks of theform disclosed in myco-pending application Serial Number 585,034; led-'Jan. 6; 415332 andin other like instances where the lock must be of small size and where economy of space and security are' im- Zportant.

Another object is to provide* a lock which is o' strongy and durable in construction, which has-.few

parts and which is notliable to get out of order.

Another object is-to providea-lock inA which all Other and `more specific objects residey in the novel construction adaptation and combination of parts hereinafter described and claimed.

The drawing `is madeto a scale Ymuch larger than the lock will usually `be in practice.

In the drawing I have shown mylock'applied-to a receptacle 10 of vsmall size forlockinga cover 1l on said receptacle. `The lock is mounted on a plate 12 which is rigidly securedtol the cover and.

is removabletherewith. i i s o .I The lock proper comprises a main frame ,plate .'13 of greater lengththan width, stamped to form In the drawing Figure 1 is afraginentary plan af'depressedportion or recess 14 which extends entirely-acrosssaid frame plate. A circular depression 15 is provided centrally withinothe recess 14 and` a small hole '.16 isprovided in the center of thedepression 15. The length of the frame plate 13 is greater fthants width and the endsy thereof are split and portions 17 are bent upwardly toform rivetl'ugs. Other portions 18, at the corners, are allowed to project outwardly be-v yond the upwardly bent rivet portions 17 vto formV a more stable bearing against the'plate 12 sto which ythe said frame plate V13 is secured. Stop lugs 19 and 19 are bent upwardly at diagonally oppositecorner'soi recess 14. v

Athrow membercomposedoia disc likev portion' 2O having a peripheral locking tongue 21 isrotatably disposed within the recess le and has a'depressed annular central portion-22 which ts into the 'recess l5. A hole 23 isprOVidedcentraIly within the depressed portion 22 and a segment ofthe depressed portion 22, preferably approxi-y mately ninety'degreesin arc, is out away leaving an opening 24 having shoulders 25 and 26 at-the respective sides thereof. Shoulders 2-7 and 28` are formed on the respective edges of the locking tongue 21 for engagement with lugs 1.9-19. One corner of Vthe lockingtongue Y21 is preferably depressed or beveled on as at 29.

A spring washer 30 is preferably provided for insertionrbetween the bottom `of the recess 1'5 and the throw member'20. l

1n assembling this lock the spring washer 30 is placed within the recess l5, the throw 20 is then placed on the spring'washer 30 with the depressed central portion 22 protruding into the recess 15 whereby s aid throw is rotatably held but can` not be displaced.- The vframe member 13 is then secured to theplate 12 by inserting'theupwardly extending rivetportions 17 through slots located at- 31 in said frame plate and riveting the same, as better shown in Fig. 3. The portions 1a which extend beyond the rivet lug portions 17 give-"a more firm bearing or footing 'againstthe plate l2 and help to resistany tendency of the' center portion of said frame 13 to spring away from the plate 12.' The spring washer 30 together with the resiliency inherent in the frame member 13 keep the throw member 20 pressed tightly up against the plate 12 at all times whereby it lwill be securely held rictionally and can not be turned except by insertion bithe proper key. s f

'iT "e throw member-'2O is adapted tobe moved rot'atively by a key V32fhaving a lug33 'nitsinner endA for engagement with the shoilders25 and-26 of-said-throw member '20.' -Two key hole slots 34 and 35 arranged at right angles to each other are provided respectively in the cover 11 and in the plate 12 which lies directly over the lock. The keyhole slot 35 preferably is positioned so that the key lug 33 will be turned into a position of non-registration with this slot 35 when the lock throw tongue 21Y is in the unlocked position. This makes it possible to use the key for lifting the lid after the lock has been unlocked, the key lug then engaging with the plate 12. The recess 24 in the throw member 20 makes-.it impossible to move the throw member into such a position as to block insertion of the key because the recess 24 can not be turned out of regis- 15 tration with the keyhole sint 35' due to the action of the stops 19 and 19. When the throw member is in the locked position and the key inserted rotation of the key in a clockwise direction will cause the key lug 33 to engage with thefshoulder 20 26 and move the lock throw clockwise until the tongue member is positioned within the recess 14 in the frame member 13 and substantially in lengthwise alignment with said frame and the shoulder 28 on the tongue member strikes against the stop 19, which stop 19 limits the clockwise movement of the throw. To move the throw member from the unlocked to the locked position the key is turned in a counter-clockwise direction so that the key lug 33 will engage with the shoul- 3`der 25 and move the throw member 20 in a counter-clockwise direction until the shoulder 27 strikes against the stop plug 19 and the tongue 21 is securely locked beneath a fixed member 36 which is rigid with the receptacle 10. The de- 35'jpressed corner 29 of the tongue 21 facilitates the entrance of said tongue under the xed member 36 and makes it possiblev to have frictional engagement of the tongue 21 with the member 36 without danger of the edge of the throw member strik- 40 against the member 36 and being blockedV from engagement thereunder. The throw member 20 is frictionally held at all times and can not become loose enough to be accidentally disengaged and the lock is free from springs and catches thus making it very cheap to build and easy to assemble.

The two keyholes at right angles to each other make the lock more diicult of access for the purpose of picking.

AThe foregoing description and accompanying gdrawing clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that such changes in the invention may be made as are fairly within the scope and spirit of the following gclamS.
